A finite subset A of an abelian group G is said to be zero-free if the identity element of G cannot be written as a sum of distinct elements from A. In this article we study the structure of zero-free subsets of Z/pZ the cardinality of which is close to largest possible. In particular, we determine the cardinality of the largest zero-free subset of Z/pZ, when p is a sufficiently large prime. Fo...
Nonvolatile, molecular multiferroic devices have now been demonstrated, but it is worth giving some consideration to the issue of whether such could be a competitive alternative for solid-state nonvolatile memory. For Fe (II) spin crossover complex [Fe{H2B(pz)2}2(bipy)], where pz = tris(pyrazol-1-yl)-borohydride and bipy 2,2?-bipyridine, voltage-controlled isothermal changes in electronic struc...
Let τD(Z) is the first exit time of iterated Brownian motion from a domain D ⊂ Rn started at z ∈ D and let Pz [τD(Z) > t] be its distribution. In this paper we establish the exact asymptotics of Pz[τD(Z) > t] over bounded domains as an extension of the result in DeBlassie [14], for z ∈ D Pz[τD(Z) > t] ≈ t exp(− 3 2 πλ 2/3 D t ), as t → ∞. We also study asymptotics of the life time of Brownian-t...
The catalytic activity of the iron(II) C-scorpionate complexes [FeCl2{HC(pz)3}] 1 (pz = pyrazol-1-yl) and [FeCl2{HOCH2C(pz)3}] 2, and of their precursor FeCl2·2H2O 3, towards cyclohexane oxidation with tert-butyl hydroperoxide was evaluated and compared in different media: acetonitrile, ionic liquids (1-butyl-3-methylimidazolium hexafluorophosphate, [bmim][PF6], and 1-butyl-3-methylimidazolium ...
اخیرا بدلیل مشکلات موجود در تهیه مخمر Lansy-PZ، امکان جایگزینی آن با انواع دیگر از مخمرها از جمله مخمر نانوایی صورت می گیرد. در این مطالعه، تاثیر شش جیره غذایی مخمری (مخمر Lansy PZ، مخمر غنی شده با HUFA، مخمر بدون لایه مانوپروتئین و غنی شده با HUFA، مخمر بدون لایه مانوپروتئین، مخمرهای ساده 100 و 50 درصد از جیره غذایی) روی ترکیب و مقدار اسیدهای چرب بدن بالغین Artemia urmiana و A. franciscana در ...
The expression of the divergently transcribed paaZ and paaABCDEFGHIJK catabolic operons, which are responsible for phenylacetic acid (PA) degradation in Escherichia coli, is driven by the Pz and Pa promoters, respectively. To study the transcriptional regulation of the inducible paa catabolic genes, genetic and biochemical approaches were used. Gel retardation assays showing that the PaaX regul...
Treatment of CuF(2) with 2 equiv of 3{5}-[pyrid-2-yl]pyrazole (Hpz(Py)), 3{5}-phenylpyrazole (Hpz(Ph)) or 3{5}-[4-fluorophenyl]pyrazole (Hpz(PhF)) in MeOH, followed by evaporation to dryness and recrystallisation of the solid residues, allows solvated crystals of [{Cu(micro-pz(Py))(pz(Py))}(2)] (1), [{Cu(micro-pz(Ph))(2)}(4)] (2) and [Cu(4)F(2)(micro(4)-F)(micro-pz(PhF))(5)(Hpz(PhF))(4)] (3) to...
BACKGROUND Multidrug resistance (MDR) is a major problem in successful treatment of cancers. Human ABCG2, a member of the ATP-binding cassette transporter superfamily, plays a key role in MDR and an important role in protecting cancer stem cells. Knockout of ABCG2 had no apparent adverse effect on the mice. Thus, ABCG2 is an ideal target for development of chemo-sensitizing agents for better tr...
A variational, self-consistent implementation of the Perdew-Zunger self-interaction correction (PZ-SIC), based on a unified Hamiltonian and complex optimal orbitals, is presented for finite systems and atom-centered basis sets. A simplifying approximation allowing the use of real canonical orbitals is proposed. The algorithm is based on two-step self-consistent field iterations, where the updat...
AIM To evaluate plasma protein Z (PZ) levels in healthy and high-risk newborn infants. METHODS A longitudinal observational study was conducted. Inclusion criteria were: healthy term and preterm newborns normal for gestational age and newborns belonging to one of the following groups: newborns small for gestational age (SGA), newborns affected by respiratory distress syndrome (RDS), newborns ...
